A Domino Approach for the Synthesis of 4-Carboxamide Oxazolines from Azirines

A regio- and the diastereoselective ring-expansion reaction of N-acyl aziridine has been described for the synthesis of 4-carboxamide oxazolines using InCl3. A domino Ugi-Joullié/ring expansion reaction of arylphenylazirines, isocyanides, and carboxylic acids led to the target product through N-acylaziridine intermediate in the presence of indium catalyst. The oxazolines were synthesized in moderate to excellent yields with high atom-economy and high bond-forming efficiency under mild reaction conditions.

In(ONf)3-catalyzed 7-membered carbon-ring-forming annulation of heteroarylindoles with α,β-unsaturated carbonyl compounds

A seven-membered carbon-ring-forming annulation occurred, upon treatment of heteroarylindoles with α,β-unsaturated carbonyl compounds in the presence of an indium catalyst. The reductive annulation was observed when octylsilane was used. With...

Conversion of dilute CO2 to cyclic carbonates at sub-atmospheric pressures by a simple indium catalyst

A simple indium halide with an ammonium salt catalyst can catalyze effectively the cycloaddition of epoxide and dilute CO2. A detailed mechanistic investigation is conducted using kinetics, isotope labeling, and in situ NMR and IR experiments.

3D hierarchical porous indium catalyst for highly efficient electroreduction of CO2

A highly porous indium electrode was prepared with a facile electrodeposition method, which delivers remarkable activity and selectivity towards electro reduction of Co2.

Indium-Catalyzed Direct Conversion of Lactones into Thiolactones Using a Disilathiane as a Sulfur Source

Indium-catalyzed reaction of lactones and a disilathiane leading to thiolactones is described. The direct synthesis of thiolactones from lactones with an appropriate sulfur source is one of the most attractive approaches in organic and pharmaceutical chemistry. In this context, we found an indium-catalyzed direct conversion of lactones into thiolactones in the presence of elemental sulfur and a hydrosilane via formation of the disilathiane in-situ. On the basis of the previous reaction, the application utilizing the disilathiane as a sulfur source was performed herein for the efficient synthesis of a variety of thiolactone derivatives from lactones by an indium-catalyst.
